I didn’t use a fan, but I did design a cooling blower for part cooling for my Smartrapcore Ali printers.

I am not good at modeling but i already have a 4cm fan so i designed this model i will try it if it didn't work i will buy a blower and use your model

In this process I realized the parts for the Smartrapcore ALU Ztop and Zbottom are not in alignment for the 8mm rod. Between the top and the bottom, they’re out of alignment of 2mm. There is an alignment issue with the belt and the pulley and the GT20 drive wheel too. I then went back and checked the onshape file and it has the same 2mm alignment issue. I’m beginning to wonder if that’s what causes some Z banding that I’ve noticed and could never solve. And I suspect the bed leveling has somewhat adjusted for this alignment issue in the Z axis.

So I’ve redesigned the Ztop and Zbottom parts, printed them last night and plan to reinstall them and see if things change. I won’t be distributing these changes as I’ve also spread the Z rods apart to the maximum width of the print bed for stability and also added an additional tab to mount on the 2020 structure to inhibit flexing over the increased distance. All of these mean I run a heavily modified Zaxis (still cantilever in design, but adjusted for stability and makes three parts that have to be printed diagonally across the bed one at a time.

My file does homing, then retract slowly for a few mm, then retracts quicker, waits 5 seconds, and then takes back the new filament inside, slowly, quickly, and again slowly when it comes to the extruder.

I don't know what I am doing wrong but it was working and now it's not working anymore.

When I send direct commands from the computer, with Repetier Host, it works flawlessly (G1 F1200 E20 extrudes 20mm quickly, but when I write it on my gcode file on the SD card, the printer does some weird things, like go 10times slower, inverting speeds...)

I have the axis control fixed, so it moves and will go through the motion of printing but extrusion still eludes me. I'm positive that it's the missing bowden coupler on the extruder that's causing a lack of pressure. I'm using the Compact Bowden Extruder from Thingiverse so I have to find out where to get a fitting that will fit it.

Any thoughts?]]>Tempest815Smart_RapTue, 28 Aug 2018 08:52:13 -0400https://reprap.org/forum/read.php?344,792346,812359#msg-812359Re: Does anyone has Step by step guide for smartrap with updated STL fileshttps://reprap.org/forum/read.php?344,792346,812359#msg-812359

See CADFiles page.

I can make plastic sets for a small fee.

I got spectra line to work, and it works fine, but it frays. I need a line that does not fray.

But I have updated the parts to be able to print a GT2 kit as an addon.

But yes, it does take a lot of attention, its not a setup and forget system.]]>orbitalairSmart_RapThu, 15 Feb 2018 11:24:26 -0500https://reprap.org/forum/read.php?344,810334,810402#msg-810402Re: SmaryRap Mini 2https://reprap.org/forum/read.php?344,810334,810402#msg-810402

I have revised the SmartRap Mini for more modern (and even cheaper) components, E3Dv6 hotend, 34mm steppers, endstops with leds.

Most importantly I have a clear set of plastic parts, all but a few redrawn in real CAD (not simply mashed and remashed STLs).
And a clear set of hardware.

I will have plastic parts kits for sale soon.
Any and all feedback is appreciated.

Pretty cheap to make, not as cheap as a tronxy x1, but now at about the $150-$200 range in raw parts prices.

Prints nice when it prints, lots of hiccups.
New marlin configs, new mounts for endstop switches on pcbs we have now, spectra fishing line, new mounts for e3dv6 hotend.
I use short 34mm steppers to get the most out of Z height.

I made mine sized to print on 8"x10" glass.

Redrew almost all the parts in SolveSpace so I could make mods. Seemed all the original stls were about 10% too small? holes too small, etc.]]>orbitalairSmart_RapTue, 06 Feb 2018 14:18:53 -0500https://reprap.org/forum/read.php?344,808711,808711#msg-808711print bed moves 13CM away from nozzle before printhttps://reprap.org/forum/read.php?344,808711,808711#msg-808711
Marlin on ramps1.4 board

I tried to calibrate the extruder stepper motor but the extruder motor is making a lot of noise.. it looks like it is trying to feed WAY faster than the nozzle can handle the plastic. It feeds and reaches a point that it is beginning to get back tension on the filament and the stepper motor jumps back to relieve the tension. So I am thinking the feed rate and/or steps per unit are wrong for the extruder. I left them at the default setting but I think it should have been lower because I am using 3mm filament. I don't see anything in documentation online about setting the feed rates according to the diameter of the filament.

As for the subject line issue ... I must be missing something .. G28 homes X and sets X=0 .. homes Y and sets Y=0 .. moves to x235 y232 .. homes Z and sets Z=0 .. last moves to z2
repeatable .. every time same sequence ends in same place.

when I load the STL for the cube .. slice it and look at it in print preview it looks fine.
I can step through the layers etc and it all seems fine

when I click print .. it does the G28 code ... It doesn't auto level (don't know why that isn't happening) and then does something weird. It moves z to 15cm above the bed. heats the hot end and starts bleeding plastic from that height while it moves back and forth.

Any ideas for me to try?

As for wiring each axis needs its motor and endstop wired up. The you can home and move the machine. Check endstops 2ork before homing. After that it's hotend heater, fan, part fan, bed heater, wire up one component at a time and test it, then move on.

Good luck they're quite satisfying machines and open to a lot of upgrading.

motion seems to be pretty accurate - when told to move 10CM in any direction it looks pretty close but haven't calibrated the steps yet

I have a photo-sensor on X and Y directions that will halt motion and Zero each direction when I click HOME in either direction.

I want to do auto leveling of the bed and bought the probe suggested online. It seems to be functioning as it will stop the motion if I put metal under the probe.... but I don't have a metal bed (plywood with glass build plate) Foil tape on the glass will be sensed. Do I have to put foil under the entire piece of glass or just under a few spots for the auto leveling to work and if I home the Z axis how to I make it go to a spot before homing so it doesn't raise the bed with no foil and hit glass on the nozzle??

I don't have the rest of the wiring hooked up yet as I am still figuring out where I want my cable runs to go so they are out of the way, but I was wondering if there is some wiring that MUST be hooked up before everything else will work?
